I think the best usecase by far is when you don't know where to start. The AI will put something out there. Either it's right in which case great, or it's wrong, and then trying to analyze why it's wrong often helps you get started too. Like to take a silly example let's say you want to build a bridge for cars and the AI suggests using one big slab of paper maiche. You reject this but now you have two good questions: what material should it have? and what shape?
